TWO-WHEELED VEHICLE.

SPECIFICATION forming part ot Letters Patent No. 350,992, dated October 19, 1886. Application filed July 23, 1886. Serial No. QOSMEO. (No modul.)

To all whom, it may concern.-

Be it known that I, VATSON F. QUINBY, a citizen of the United States, residing at Wilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Vehicles; and I do declare the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to two-wheeled vehicles or sulkies 5 and it consists in an improved spring-connection between the wheel-axle and shafts and the vehicle-body. The shafts are rigidly connected tothe wheel-axle, and upright frames are erected on the shafts above the axle, from which the vehicle-body is sus pended by spiral or coiled springs. The springs are attached to the upright frames on each side at a single point only, so that the vehicle-body is free to swing to any extent, the result being that the body always assumes a horizontal position irrespective of the position of the shafts. Check-straps are provided, which are connected to the axle and to the bottom of the body, to prevent the latter from being thrown forward and its lateral move'- ment.

The invention is illustrated in the accompanying drawings, in which Figure l is a side View of the vehicle, Fig. 2, a plan view of the same; Fig. il, a rear view of one of the upright frames, and Fig. 4 a bottom view showing the arrangement of the check-straps.

A is the axle; B B, the wheels, and C C the shafts, which are rigidly connected to the axle and extend behind the same. Forward and .back of the axle the shafts are connected by cross-bars D D, and the latter are also connected by longitudinal bars E E, parallel with and close to the shafts. The upright frames F F are attached to and supported by the shafts and longitudinal bars. Each upright frame consists of four upwardly-extending strips, a (L b, and a horizontal strip, c, sup- .ported by said strips at their upper ends. The

two strips c a are attached to the longitudinal bar, and are inclined vertically toward each other, but are not inclined laterally. The two strips b b, which are attached to the shaft, not only incline toward each other, but also toward the strips a a.

G is the vehicle-body, of any desired construction, being shown as having a floor, d, dash-board e, and seat f. Then the vehicle is in use, the floor ofthe body is just above the plane of the shafts, and the body is suspended within the frames F F and between the crossbars D D. rIhe body is suspended from the cross-strips c c of the upright frames on each side by coiled or spiral springs H H. There are two of these springs on each side, which are both connected to a single shackle attached to the center of the cross strip c directly ab've the axle. These springs are inclined away from each other, and are connected to the licor of the vehiclebody some distance apart on either side of the axle. By thus suspending the body it is brought as close as possible to the axle, so that it is subject to the minimum amount of movement due to the ordinary incidents of the movements of the horse andthe inequalities of the road, and being suspended from a single point on either side, the tloor of the body always assumes a horizontal position irrespective of the position of the shafts, so that even if the shafts rested on the ground the body would remain horizontal. The springs themselves prevent the jarring and `jolting from being transmitted to the vehicle-body.

To prevent the vehicle-body from swinging laterally beyond reasonable limits, side checkstraps, I I, are provided. These straps are secured to the center of the axle, and pass through eyes at the sides of the floor o1' the vehicle. To prevent the vehicle-body being tilted forward, a similar back check-strap, J, is provided, which is secured to the center ot' the axle and to the back of the vehicle-body. The several checkstraps can be shortened or lengthened, as desired, to regulate the extent of movement. These check-straps may be made more or less elastic, if so desired.

Although the method of suspending vehiclebodies herein described is more particularly adapted and designed for two-wheeled vehicles, it is not intendedto limit the scope of l Vby and upon said shafts, in combination with the Vehicle-body suspended from said upright frames, said springs being connected to the frames on either side at a single point7 suhstantially as set forth.

3. The axle of a vehicle, the shafts rigidly secured thereto, longitudinal bars parallel Witlrand close to said vshafts, and upright frames supported by said shafts and longitndinal bars, each frame consisting,` of verticallyextending strips attached to said shafts and bars, and a erosshorizontal strip connecting the vertical Strips, in combination with the vehicle-body suspended from said horizontal lstrips, substantial] y as Set forth.

4. rlhe axle and shafts of a Vehicle7 upright frames supported by said shafts, and a vehiele-body suspended from a single point on eaeh upright frame by coiled springs, in combination with a back cheek-Strap eonneeted to the axle and to the rear of the vehicle-body, Substantially as set forth. Y

In testimony whereof I affix my signature in presence of two Witnesses.
